BADAN is a thiol-reactive, environment-sensitive fluorescent probe used for site-specific labeling of protein cysteine residues to detect protein topology, local polarity, protein-lipid interactions, and conformational changes. The bromoacetyl group of BADAN covalently binds to cysteine thiols, and its fluorescence originates from the intramolecular charge transfer (ICT) excited state. The emission peak position varies with the polarity of the surrounding medium: it blue-shifts to approximately 488 nm in nonpolar environments (such as the hydrophobic core of lipid bilayers) and red-shifts to approximately 496-507 nm in polar environments (such as aqueous phases), independent of enzymes, pH, or membrane potential. Ex = 380-402 nm; Em = 400-600 nm .

DCA-Mln is a Fluorescent probe for ferric iron (Fe³⁺) detection. The probe works via an internal charge transfer (ICT) process from its diethylamino group to its dicyano group, which produces bright pink fluorescence in its unbound state; when Fe³⁺ is present, two molecules of DCA-Mln chelate with one Fe³⁺ ion, with one cyano group of each DCA-Mln participating in the complexation, and this binding triggers a photoinduced electron transfer (PET) process that provides a nonradiative deactivation pathway, resulting in fluorescence quenching; additionally, the probe exhibits a visible color change from purple to peach pink upon Fe³⁺ binding, enabling dual-channel detection. The probe has an excitation wavelength of 570 nm and an emission wavelength of 670 nm, and it shows a rapid response, with fluorescence stabilizing within 15 seconds of Fe³⁺ addition. DCA-Mln is cell-membrane-permeable, nontoxic at the imaging concentration of 10 μM, and can be used for Fe³⁺ detection in actual water samples, Fe³⁺ imaging in living cells, and as an anti-counterfeiting ink[1].

Mito-CS1 is a fluorescent probe for imaging and reversible detection of the exchangeable mitochondrial Cu + pool in living cells. Mito-CS1 combines a Cu +-responsive fluorescent platform with a mitochondria-targeted triphenylphosphonium group, which localizes the probe to mitochondria via a proton gradient. Mito-CS1 contains a thioether-rich receptor for the selective recognition and binding of Cu +, triggering a fluorescence turn-on response by inhibiting photoinduced electron transfer. The apo-form of Mito-CS1 has excitation/emission wavelengths of 555/569 nm, while those of Mito-CS1 after binding to Cu + are 550/558 nm .

N-Methylfulleropyrrolidine serves as an electron acceptor molecule characterized by its fullerene core and a nitrogen-free lone pair associated with the pyrrolidine ring. This compound can act as an intermediate in the synthesis of various functionalized fullerenes and plays a significant role in the development of opto-electronic devices. Comprehensive studies have been conducted on the photoinduced energy and electron transfer processes between oligothienylenevinylenes and N-Methylfulleropyrrolidine (MP-C60).

TPEP-6-NH-MA is a Fluorescent probe that selectively detects cysteine (Cys) and homocysteine (Hcy) without interference from glutathione (GSH) and other amino acids, and can also be used for bioimaging of biothiols in living cells. Its detection mechanism relies on terminating the photoinduced electron transfer (PET) effect via a Michael addition reaction between the maleimide recognition moiety and the thiol group of Cys or Hcy. The excitation wavelength of TPEP-6-NH-MA is Ex = 361 nm .

CFSE-Tz is a fluorescent bioorthogonal probe constructed based on the IEDDA reaction, which is mainly used for visual tracing of amino acid uptake in living cells. The tetrazine group within the CFSE-Tz molecule quenches CFSE fluorescence via photoinduced electron transfer; after the probe specifically undergoes a bioorthogonal reaction with trans-cyclooctene-modified amino acids, the quenching effect is eliminated, and a green fluorescent signal is released, thereby dynamically monitoring the intracellular amino acid uptake process. CFSE-Tz can be applied to in vitro single-cell fluorescence imaging and studies related to amino acid metabolism in tumor cells (Ex = 495 nm, Em = 519 nm) [1] [2].

Si-DMA is a far-red fluorescent singlet oxygen probe (Ex/Em = 640/690 nm). After reacting with singlet oxygen, Si-DMA forms an endoperoxide with a 17-fold fluorescence enhancement. Si-DMA localizes selectively to mitochondria with negligible auto-oxidation. Si-DMA can be used for high spatiotemporal resolution visualization and detection of mitochondrial singlet oxygen in living cells .
